摘 要:文章介绍了某采深840m煤矿扩大区的地应力实测结果,分析了地应力的分布特征和对巷道布置及稳定性的影响,采用最大水平主应力与巷道布置的方向进行支护设计,实施了对称非对称联合支护技术,取得了良好的支护效果。This paper introduced the measured results of in - site stress in some mine expand region. Distribution characteristics of in - site stress in this area and its influence on layout and stability of roadway was analyzed. The support design is based on maximum horizontal main stress and its directionality to roadway layout. Symmetrical and non symmetrical combined support technology was carried out and good resuh of support has been reached.
